CLI Overview | blurkit

When to use

Use the CLI when you want JSON output without writing a custom script.

Example

blurkit encode ./public/hero.jpg --pretty

Inputs / Options / Behavior

Command surface:

blurkit encode <input>

Common flags:

--algorithm blurhash|thumbhash
--size <number>
--width <number>
--height <number>
--format png|jpeg
--glob <pattern>
--out <file>
--base-path <path>
--concurrency <number>
--backend sharp|wasm
--pretty

Behavior:

Limits / Caveats

--backend sharp requires sharp.
--backend wasm supports PNG/JPEG/WebP decode.
--backend wasm requires blurkit-wasm-codecs installed.
--glob is valid only for local directory input.
